LP Dual 2 Stage Regulator

[dabber]

Have a LP Dual 2-stage Auto/Change over regulator. Question is can one run only one tank on the system. When I have a single tank on with the valve open, there is gas leaving from the open connection. It doesn't matter which direction the switching valve is pointing.

Is my valve defective or is it only designed to run two tanks at the same time?

I don't think you run two tanks at once, you just need to have 2 tanks hooked up.

On my system you can have one full tank and the other can be empty and it runs fine, just needs to be hooked to a tank and not an open end.

Yea -

Thats my point, the down side of this set up is that you must have two tanks hooked up at all times, whether full or not.

I have the same set up on my house. I have taken one tank in to get filled and never lose any gas from the other tank. Do you have a valve with a arrow that you need to turn toward the full tank???

[dabber]

yea I do. When I point the arrow at the full tank, disconnect the empty, turn the LP valve on, the LP gas comes out of the disconnected line. Must be defected, or do I have to have a tank on at all times?

Sounds like it is defective, I would replace it. When you turn the arrow to the full tank or the one being used it should not come out of the exposed end once you take the tank off that isn't being used.

Mine does the same thing.

I have a dual tank system and mine does the same thing. I asked the camper company they told me it was normal, that you needed to have 2 tanks on there, although it would only draw from one.

mine does not lose gas when I take the empty off. Must be something wrong.

get one of those steak savers and screw a 1 pound disposable to it till ya get back with the other refilled or get a plug it should be 1/4 " brass as I recall

Here's what I've found. The initial hook up needs 2 tanks. It doesn't matter if one is empty or full. Now, when it's all hooked up, gas is turned on, and the arrow is switched to the full tank, I can take the empty off without loosing gas out of the empty pig tail. Seems weird, but that's how it works with my auto switch reg. I wonder if there's a membrane that needs to be closed with pressure to seal off the empty side.

I haven't tried this method for extended periods of time, but doing it this way has worked for the last 4 yrs without issue.

Dumb question but I have seen a guy do it before..... Do you have the arrow the right way....
